SSAS でExact Online Data に連携するOLAP Cube を作成

Connect to Exact Online data in an Analysis Services project using the Exact Online Data Provider and build OLAP cubes for use in analytics, reporting, and more.

SQL Server Analysis Services (SSAS) is an analytical data engine used in decision support and business analytics. It provides enterprise-grade semantic data models for business reports and client applications, such as Power BI, Excel, Reporting Services reports, and other data visualization tools. When paired with the CData ADO.NET Provider for Exact Online, you can create cubes from Exact Online data for deeper and faster data analysis.

This article walks through creating an Analysis Services project in Visual Studio to build and deploy a multi-dimensional model of Exact Online data. You will need to have an accessible SSAS instance and the ADO.NET Provider installed.

Creating a Data Source for Exact Online

Start by creating a new Analysis Service Multidimensional and Data Mining Project in Visual Studio. Next, create a Data Source for Exact Online data in the project.

In the Solution Explorer, right-click Data Source and select New Data Source.

Opt to create a data source based on an existing or new connection and click New.

Exact Online uses the OAuth authentication standard. The InitiateOAuth connection property facilitates the OAuth flow -- by default, this is set to GETANDREFRESH. You can also use the embedded OAuth credentials or you can register an OAuth app with Exact to obtain your own.
In addition to the OAuth values, provide the Region. If Division is not set, the default Division is determined.

See the "Getting Started" chapter of the help documentation for more information.

When you configure the connection, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Based on the foreign key match scheme, relationships in the underlying data will be automatically detected. You can view (and edit) these relationships by double clicking Data Source View.

Note that adding a secondary data source to the Data Source View is not supported. When working with multiple data sources, SSAS requires both sources to support remote queries via OpenRowset which is unavilable in the ADO.NET Provider.

Creating a Cube for Exact Online

The last step before you can process the project and deploy Exact Online data to SSAS is creating the cubes.

In the Solution Explorer, right-click Cubes and select New Cube

Select "Use existing tables" and click Next.

Select the tables that will be used for measure group tables and click Next.

Select the measures you want to include in the cube and click Next.

Select the dimensions to be created, based on the available tables, and click Next.

Review all of your selections and click Finish.

Process the Project

With the data source, data source view, and cube created, you are ready to deploy the cube to SSAS. To configure the target server and database, right-click the project and select properties. Navigate to deployment and configure the Server and Database properties in the Target section.

After configuring the target server and database, right-click the project and select Process. You may need to build and deploy the project as a part of this step. Once the project is built and deployed, click Run in the Process Database wizard.

Now you have an OLAP cube for Exact Online data in your SSAS instance, ready to be analyzed, reported, and viewed. Get started with a free, 30-day trial of the CData ADO.NET Provider for Exact Online.
